Definitions

  • the present invention relates generally to electrical busses, and, more particularly, to a bussplate for an electronic controller in a motor vehicle.
  • Motor vehicles and in particular an automotive vehicle, frequently incorporate electronic components, such as an electronic controller, to functionally communicate with various systems in the automotive vehicle.
  • an engine controller functionally communicates with the engine and engine-related systems
  • a vehicle body controller functionally communicates with vehicle body-related systems.
  • Motor vehicles also contain other well known electronic components, such as a radio, or a compact disc player, or a cellular phone.
  • a filtered electrical connector having a die cast aluminum housing is mounted to a printed circuit board, for attaching a wiring harness to the printed circuit board.
  • the die cast housing includes a plurality of compartments, with a filter insert contained within each compartment, for filtering electronic noise. While the filter insert works well, it does not completely shield an opening in the housing for an electrical connector.
  • a bussplate is used to commonize electrical current in electrical circuits. It is also known in the art that all electrical circuits must be grounded to a common ground.
  • multiple unique internal and external ground interfaces are typically utilized to ground individual components including the connector, filter insert, printed circuit board or housing.
  • a pin may be cast in the housing to ground the filter insert to the housing.
  • a grounding clip may be used to ground the printed circuit board to the metal housing.
  • An external ground, such as a cable, connector may ground the housing to a massive conductive structure, such as the engine.
  • a housing made from a material, such as a die cast aluminum may be subject to corrosion.
  • a bussplate that integrates multiple ground interfaces, while providing filtering and shielding from electrical noise and electromagnetic interference within a non-corrosive enclosure.
  • the present invention includes a bussplate.
  • the bussplate includes a plate having a plurality of integral electrical ground interfaces for commonizing electrical ground current within the electronic device.
  • the plate filters the electronic device from electronic noise and shields the electronic device from electromagnetic interference.
  • a bussplate for an electronic controller is provided that integrates multiple ground interfaces.
  • the bussplate filters and shields the electronic controller from unwanted noise or other electrical interference.
  • the housing for the electrical controller can be made from a non-corrosive material, such as plastic.
  • the electronic controller 10 is an engine controller on a motor vehicle (not shown), and in particular an automotive vehicle.
  • the electronic controller 10 includes a housing 12 and a cover (not shown) attached to the housing 12.
  • the housing 12 has a generally rectangular, planar shape and is made of a metal material such as aluminum.
  • the housing 12 can be made from a deep drawn aluminum material instead of die cast aluminum.
  • the electronic controller 10 also includes a printed circuit board 14, as is known in the art, disposed on the housing 12.
  • the electronic controller 10 also includes an electrical connector 16, such as a filtered electrical connector, mounted to the housing 12, for attaching a wiring harness (not shown) to the printed circuit board 14, for electrically communicating between the printed circuit board 14 and another component (not shown) in the automotive vehicle.
  • the electrical connector 16 includes a filter insert 17 disposed between the electrical connector 16 and the printed circuit board 14.
  • the filter insert 17, as is well understood in the art, is a secondary component used to filter electronic noise in an electrical circuit.
  • the filter insert 17 filters unwanted electrical noise from passing through the connector 16 to the printed circuit board 14.
  • the housing 12 includes at least one aperture 18 for receiving a bussplate 20, according to the present invention.
  • the bussplate 20 is a stamped, conductive, metal plate having a plurality of ground interfaces 22 for grounding the electronic controller 10 to a common ground (not shown) in the automotive vehicle.
  • the common ground is an engine ground.
  • the bussplate 20 serves as a filter for the electrical connector 16, and a shield for the opening 18 for receiving the bussplate 20 in the housing 12.
  • the bussplate 20 is a plated metal, such as tin plated over brass.
  • the ground interfaces 22 includes a first ground interface 24, which electrically grounds the filter insert 17 disposed on the first ground interface 24, to the bussplate 20.
  • the first ground interface 24 includes a plurality of blades 26 extending radially from the bussplate 20.
  • the blades 26 are press fit into openings 28 in the filter insert 17.
  • the blades 26 are generally rectangular in shape.
  • the outermost end of the blade 30 is slightly narrower than the other end. It should also be appreciated that, in this example, the first ground interface 24 includes three parallel rows having four blades 26 each.
  • the ground interfaces 22 also includes a second ground interface 32, that electrically grounds the bussplate 20 to the engine ground of this example.
  • the second ground interface 32 is a blade 34 extending radially from the bussplate 20 into an aperture in the electrical connector 16.
  • the blade 34 is electrically grounded to a ground in the wiring harness (not shown), which in turn is electrically connected to the engine ground.
  • the ground interfaces 22 also include a third ground interface 38.
  • the third ground interface 38 is a radially extending blade 40 of sufficient length to pass through an opening 42 in the printed circuit board 14.
  • the blade 40 is soldered to the printed circuit board 14 to electrically ground the printed circuit board 14 to the bussplate 20.
  • the third ground interface 38 includes two blades 38, each having a rectangular shape, that is slightly tapered.
  • the ground interfaces 22 further include a fourth ground interface 44 to electrically ground the housing 12 to the bussplate 20.
  • the fourth ground interface 44 is a blade 46 extending radially from the bussplate 20.
  • the fourth ground interface 44 includes four pairs of blades 46.
  • a tip 48 of the blade 46 tapers to a point so that the blades 46 bite into the housing 12 when the electronic controller 10 is assembled, to complete the electrical connection.
  • the electrical connector 16 is attached to the housing 12, such as with screws (not shown).
  • a plurality of pins are inserted into openings 50 in the electrical connector 16, and the bussplate 20 is disposed on the housing 12, such that the pins pass through corresponding openings 52 in the bussplate 20.
  • the blades 46 from the bussplate 20 bite into the housing 12 to ground the bussplate 20 to the housing 12.
  • the filter insert 17 is positioned over the bussplate 20, such that the blades 26 fit into corresponding openings 28 in the filter insert 17 and the pins pass through their corresponding openings 54 in the filter insert 17.
